"Your Totem Animal won’t be in there to help you. You’ll be on your own. The Pain Cave is for cowards."
These are the words that greeted me when I went to do my Mobility Workout of the Day last night. You can understand my confusion, I'm sure, but the point Kstar is making is a good one and I think I'll be taking it to heart. "The Pain Cave" is a euphemism for that moment of stubborn enthusiasm some athletes get where, in their determination not to look or feel weak, they push themselves well past the limits their body can handle and they ignore the pain signals their muscles are tapping out in panicked Morse code.
The Pain Cave is Dumb. Don't be dumb. If it hurts, then stop!!!
